RESUMO
COVID-19 caused by the novel coronavirus SARS-CoV-2 led to the pandemic, causing unprecedented health and social crisis worldwide. Acute coronary syndromes patients, especially when coronary artery bypass graft (CABG) surgery is needed, may present with higher severity risk if affected by COVID-19. Extracorporeal circulation leads to activation of endothelium and microcirculatory network, which activates the coagulation, platelet aggregation and inflammation 1. COVID-19 may also course with severe inflammation, massive secretion of inflammatory cytokines, plaque rupture and a procoagulant state 2. Therefore, it is advisable to postpone surgeries interventions when possible. However, our institution is a public tertiary referral hospital for high-risk cardiovascular patients even in SARS-CoV-2 pandemic. We describe a series of thirteen high risk coronary artery disease patients submitted to CABG and who had COVID-19 infection during the same hospitalization, six patients had COVID-19 before surgery, three patients were operated with active infection and four patients were infected after surgery
